Nuclear Moon Bases

When lunar astronauts flick on their televisions after a long day of prospecting, they’ll have a trashcan-size nuclear reactor to thank for their nightly dose of prime time. NASA, looking past the already daunting task of simply getting humans to the moon by 2020, recently started considering proposals for ways to power lunar habitats. Batteries and fuel cells provide only short-term solutions. Solar power would be limited where a single night lasts as long as 354 hours. So space-agency officials have started making plans to go nuclear.
The outline for the Fission Surface Power (FSP) plan is fairly straightforward: An underground, uranium-powered nuclear reactor produces heat and drives a power converter to generate electricity. The nuke plant would churn out 40 kilowatts of electricity, enough power to provide life support to four astronauts with plenty left over to mine oxygen from lunar soil and run moon buggies.
